Is there a way how to do it without reconfiguring gcc?  This question
aims at the following situation: I already have compiled the stage1
compiler with a patch, and I have learned from some external source
that the compiler ICEs during the compilation of libjava.  Since it
is highly unlikely that bootstrapping the compiler would matter,
I would like to be able to just start building libjava using stage1
compiler.  Reconfiguring gcc and building it from scratch takes
some time, so I would like to avoid that.

Would it be possible to add a possibility to just clean up the things,
without restarting the bootstrap (i.e., to move everything to the
state I would have after "make stage1-bubble" if I started from the scratch)?
